When Sir Bors saw that he must fight with his brother or else die, he wist not what to do. Then his heart counselled him not to fight, inasmuch as Lionel was born before him, wherefore he ought to bear him reverence. Again kneeled he down afore Lionel's horse's feet, and said, "Fair sweet brother, have mercy upon me and slay me not, and have in remembrance the great love which ought to be between us twain."
What Sir Bors said Lionel recked not, for the fiend had brought him in such a will that he was determined to slay him. Then when Lionel saw he would none other, and that he would not rise to give him battle, he rushed over him, so that his horse's feet smote Bors to the earth, and hurt him so sore that he swooned of distress. When Lionel saw this, he alighted from his horse to smite off his head. So he took him by the helm, and would have rent it from his head, had not the hermit come running unto him, which was a good man and of great age. Well had he heard all the words that were between them, and so fell down upon Sir Bors.
Then he said to Lionel, "Ah, gentle knight, have mercy upon me and on thy brother, for if thou slay him thou shalt commit a deadly sin, and that were sorrowful; for he is one of the worthiest knights of the world, and of the best conditions."
"So God me help," said Lionel, "sir priest, unless ye flee from him I shall slay you, and he shall never the sooner be quit."
"Verily," said the good man, "I had rather ye slay me than him, for my death shall not be great harm, not half so much as his."
"Well," said Lionel, "I am agreed"; and he set his hand to his sword, and smote the hermit so hard that his head went backward.
For all that, he restrained him not of his evil will, but took his brother by the helm, and unlaced it to strike off his head. And he would have slain him without fail, but so it happened that Colgrevance, a fellow of the Round Table, came at that time thither, as our Lord's will was. First he saw the good man slain, then he beheld how Lionel would slay his brother, whom he knew and loved right well. Anon he sprang down and took Lionel by the shoulders, and drew him strongly back from Bors, and said, "Lionel, will ye slay your brother, one of the worthiest knights of the world? That should no good man suffer."
"Why," said Sir Lionel, "will ye hinder me? If ye interfere in this, I shall slay you, and him after."
Then Lionel ran upon Bors, and would have smitten him through the head, but Sir Colgrevance ran betwixt them, and said, "If ye be so hardy as to do so more, we two shall meddle together."
Then Lionel defied him, and gave a great stroke through the helm. Now Colgrevance drew his sword, for he was a passing good knight, and defended himself right manfully. So long endured the battle that Sir Bors awoke from his swoon, and rose up all anguishly, and beheld Sir Colgrevance, the good knight, fight with his brother for his quarrel. Then was he full sorry and heavy, and would have risen to part them. But he had not so much might as to stand on foot, and must abide so long till Colgrevance had the worse, for Sir Lionel was of great chivalry and right hardy.
